Manufacturer description
The StarTech.com TX3 Fan Power Y Splitter Cable solves a specific problem in older and compact PC builds: a motherboard or power supply that offers fewer 3-pin fan headers than you have fans. This 12-inch cable takes a single 3-pin internal power connection (male) and splits it into a female 3-pin TX3 connector pair, letting you run two case fans from one source. That matters most in retro PC builds and vintage cases, where 3-pin TX3 headers are the norm and board-level fan control is limited. At 12 inches, the cable gives you enough slack to move a fan away from its nearest header, so you…

Frequently Asked Questions
Can I run two case fans from one motherboard header with this?
Yes. The cable converts one 3-pin internal power connection into a pair of 3-pin TX3 connections, which is exactly what it is designed for: connecting two 3-pin TX3 fans to a single power supply connector.
How long is the StarTech TX3 splitter cable?
12 inches. That length is meant to give you enough slack to re-position case fans for better airflow instead of mounting them wherever the nearest header happens to be.
Will this work with 4-pin PWM fans?
It is specified as 3-pin internal power (F) to 3-pin internal power (M), so it targets 3-pin TX3 fans. For 4-pin PWM wiring, check the product listing for a PWM-specific splitter instead.
Does the splitter come with a warranty?
Yes. StarTech.com backs this cable with its lifetime warranty. Check the product listing for the current terms and claim process.
